NAME

uhso -- support for several HSxPA devices from Option N.V.

SYNOPSIS

The module can be loaded at boot time by placing the following line in
loader.conf(5):
uhso_load="YES"

DESCRIPTION

The uhso driver provides support for several HSxPA devices from Option
N.V. that are based on their packet interface. Each device has a set of
serial ports and a raw IP packet interface. The serial ports of the
device are accessed through the ucom(4) driver which makes them behave
like tty(4) devices. The packet interface is exposed as a network
interface.
Establishing a connection on the packet interface is achieved by using
the proprietary AT commands ``AT_OWANCALL'' and ``AT_OWANDATA'' on any of
the available serial ports.
The network interface must be configured manually using the data obtain
from these calls.
Each device usually have at least two or more serial ports, their
individual purpose can be identified through sysctl(8). Ports identified
as ``Modem'' features a normal modem interface that can be used with PPP.
Ports identified as ``Diagnostic'' uses a proprietary binary interface
used for firmware upgrades, this port does not have a AT command
interface and can not be used to control the device. Other ports
features an AT command interface that can be used for normal device
control.

HARDWARE

The uhso driver should work with most devices from Option. The following
devices have been verified to work
+o Option GlobeSurfer iCON 7.2 (new firmware)
+o Option iCON 225
+o Option iCON 452
+o Option iCON 505
The device features a mass storage device referred to as ``Zero-CD''
which contains drivers for Microsoft Windows; this is the default mode
for the device. The uhso driver automatically switches the device from
``Zero-CD'' mode to modem mode. This behavior can be disabled by setting
hw.usb.uhso.auto_switch to 0 using sysctl(8)
